A dataset containing the height of 15 pairs of the offspring of maize plants.
cornheight
A data frame with 15 pairs of observations and three variables:
Pair number, a numeric vector
Height of cross-fertilized plants, a numeric vector
Height of self-fertilized plants, a numeric vector
Darwin took 15 pairs of Zea Mays plants, where within each pair the two plants were of exactly the same age, were subjected from the first to last to the same conditions, and were descended from the same parents. One individual in each pair was cross-fertilized and the other was self-fertilized. The heights of offspring were then measured to the nearest eighth of an inch. This data set was used by Fisher (1935) to introduce the idea of the randomization test with paired comparison data.
